Day in the Life: Legal Engineer at :Harvey:
What it’s like to be a Legal Engineer at Harvey, helping firms and in-house teams apply AI to real legal workflows.
Legal Engineers at Harvey are former practicing lawyers who help prospects and customers discover the real impact of AI. This post explains what a Legal Engineer at Harvey does in practice, and why it’s a great career opportunity for tech-forward lawyers.
What Does a Legal Engineer do?
Legal Engineers are experienced lawyers — typically trained at top-tier firms and in-house companies — who work directly with Harvey's customers and prospects to show how AI fits into real legal workflows. They partner with law firms and in-house teams throughout their Harvey journey, bringing legal expertise and judgment to every interaction.
“The key thing about my role is helping lawyers leverage AI effectively in a way that makes sense in their day-to-day. It’s about helping our customers work smarter and I love that about my job.”

Common projects include identifying high-value use cases for AI, building agents, and refining prompts. During a pilot, a prospect says "I'm trying to analyze these credit agreements in Harvey and it's not quite working." The Legal Engineer goes into Harvey, loads the prospect's actual documents, and builds a prompt, or a multi-step workflow, that gets the output right. They test it, refine it, and send it back.
Legal Engineers may also run onboarding and training for customers, helping teams quickly get comfortable using AI in their day-to-day workflows. They design practical, use-case driven sessions that walk users through real matters, templates, and processes so the value shows up immediately.
The title Legal Engineer sounds technical, but the real skill is legal. Understanding what the prospect or customer is actually trying to accomplish, what matters in the output, and where the edge cases are: that comes from having done the work as a lawyer. Our job at Harvey is to train Legal Engineers on how the product works and empower them to guide customers with their own expertise.
How is the Team Structured?
Harvey's Legal Engineering team spans the US, Canada, Latin America, Europe, and Asia-Pacific. As Harvey grows globally, Legal Engineers are some of the first hires in new markets to make sure prospects and customers get local, hands-on support and expertise.
The team operates across three tracks:
Pre-Sale Legal Engineers partner with our Sales Account Executives throughout the sales process, from early discovery through a prospect's pilot. They lead practice-area-specific demos, help prospects understand how Harvey fits into their daily work, and build trust with the team. They own the legal credibility in the sales motion.
Legal Engineering Product Specialists (Post-Sale) take over once a deal closes. They partner with our Customer Success team to guide customers on using Harvey. That may look like running onboarding and training, tracking usage, identifying which teams are getting value and which need more support, and building custom workflows. Their success is measured by whether the product actually changes how a firm works.
Legal Engineer — Custom Solutions is a more specialized track focused on building complex, multi-step workflows and playbooks for customers with sophisticated, high-volume needs.
What Kind of Person Does Well in this Role?
The lawyers who thrive in this role are intrigued by where AI is taking legal work, comfortable in high-volume customer-facing environments, and willing to experiment. Harvey is a startup and there is a level of ambiguity that comes with that. The best Legal Engineers at Harvey embrace uncertainty and know that change is a constant when it comes to technology today.
“My advice to lawyers joining :Harvey: is to come with an open mind. AI moves at the speed of light and :Harvey: is evolving as it happens. You need to be excited by change and by the opportunity ahead.”

Why Should Someone Pursue This Role?
For lawyers thinking about a move, a few things are genuinely different at Harvey.
Your legal expertise is the job. Being a former M&A associate or litigator isn't experience you're stepping away from. It's what makes you effective in every conversation and builds credibility with our customers. The deeper the legal background, the more you can do with it.
The scope of impact is wide. When a Legal Engineer works with a firm and changes how their contract review or due diligence process works, they see it directly, and it scales across hundreds of lawyers at dozens of firms globally.
The timing matters. Harvey works with more than half the AmLaw 100 and is expanding quickly across EMEA and APAC. Experience practicing law at a high level, combined with real curiosity about AI, is a rare combination right now. This career category didn't exist five years ago. The people who join Harvey now are building what that role looks like.
We're hiring Legal Engineers across the US, EMEA, and APAC. Please visit our Careers page to learn more and apply today.
